  • Patent number: 11682125
    Abstract: A fluorescence image registration method includes obtaining at least one fluorescence image of a biochip. An interior local area. Sums of pixel values in the interior local area along a first direction and a second direction are obtained. A plurality of first template lines is selected to find a minimum total value of the sums of pixel values corresponding to the first template lines. Pixel-level correction is performed on a local area of the track line to obtain a pixel-level track cross. Other track crosses on the biochip is obtained, and the pixel-level correction is performed on the other track crosses. The position of the pixel-level track line is corrected by a center-of-gravity method to obtain the subpixel-level position of the track line. The subpixel-level positions of all sites uniformly distributed on the biochip is obtained.

The antenna comprises a substrate and an antenna array arranged on the surface of the substrate, a first antenna element and a second antenna element are cascaded in an x-axis direction by a filter phase-shift line so as to form a subarray. A pair of T-shaped monopoles are symmetrically placed along the x axis at a certain distance above and below each of the first and second antenna elements, respectively, and a rectangular slot is embedded in the upper edge of the second antenna element to achieve good impedance matching. The second antenna element generates a fan beam at one frequency point or frequency band to have the performance of a wide beam, and generates a pencil beam at another frequency point or frequency band to have the performance of a narrow beam.

    Abstract: The present invention relates to a recombinant antigen and an isolated polynucleotide of porcine reproductive and respiratory syndrome virus (PRRSV), a composition including the same and a method of making the same. The recombinant antigen is a chimeric protein of PRRSV dual structural proteins and T-cell epitope. The polynucleotide encodes an amino acid sequence of the recombinant antigen. The recombinant protein expressed by the polynucleotide in an eukaryotic expression system can be beneficial for mass production and purification. An immunogenic composition including the recombinant antigen can promote pro-inflammatory M1-phenotype polarization of porcine alveolar macrophages (PAMs), reduce receptor CD163 expression that is mediated for viral entry and activate T helper (Th1) immune responses, thereby being applied to a vaccine composition against PRRSV.
